Joey the caps that are known as the "cpu caps" are simply a 1V8 rail. That line goes to every single IC on the board including RAM, CPU, MAX77620, MAX77812, M92T36, MAX17050, Backlight IC, LCD driver, game card PMIC, audio IC etc. Just because that cap is short doesn't mean the board is dead. It could be a number of issues causing that short. Take another look mate. Generally if the CPU is dead the CPU will get immediately hot with just the battery plugged in, even if the battery is virtually dead

Just pinned your comment pal so hopefully it rectified any information for anyone watching going forward ☺️ Thanks for the feedback once again! Out of interest, would you just remove all of the components you’ve named one by one until the short has gone? Or is there individual ways to measure the components you’ve listed before having to remove them?

@@JoeyDoesTech good stuff mate, didn't want to sound like a know it all but there's too many people who are under the impression that it always means a dead cpu and it's not the case. You can try injecting 1v but a lot of the time I just remove components until the short disappears. It could still be the CPU but as I said it's not always the case

@@JoeyDoesTech The two "shorted" caps around the MAX ic (the one South the CPU) are just low impendence, around 20 Ohm. Alsways use resistance Mode to Check back. Only if it's under 10 Ohm you can Tell it's a short. Also the middle cap left of the backsidr Max ic is low (same line as the other 2 caps)

I'm guessing the shop knew the cpu is dead? Hence why the switch look as mangled as it is. I really like today's video. Very informative

Or another possibility is the shop botched it and didn't try putting it back together before shipping it to customer and just told him it was already present.

Appreciate your taking the time to walk through this. Your initial assumption of bad cpu was correct and it is helpful to have it confirmed. Next time those particular caps are shorted, you should be safe to assume bad cpu and move on to something else. Great video!

Again, thank you so much Joey for upload this kind of videos, really enjoyable

Unfortunately as soon as I saw the repair shop took 4 months to get back to the customer I knew they messed it up beyond repair and might have been waiting for a board to replace it. You are right Joey as soon as you measure shorts on those two caps the board can be tossed.

That's incorrect mate. The caps that are known as the "cpu caps" are simply a 1V8 rail. That line goes to every single IC on the board including RAM, CPU, MAX77620, MAX77812, M92T36, MAX17050, Backlight IC, LCD driver, game card PMIC, audio IC etc. Just because that cap is short doesn't mean the board is dead. It could be a number of issues causing that short. Most of the misconceptions about the CPU being definitively dead are a myth created by a bunch of phone techs who don't know what they're talking about. I don't want to sound like a d**k but people need to stop spreading this myth.

One thing I see being overlooked is the Maxx IC. It is a power management BGA chip, which means you may need to get into some basic re-balling. it is actually quite easy.. Ask Phil where he got his latest stencils for solder pastie. Cheers Joey!

Nice diagnostics skills right there. Only thing I would of done to save lots of time is inject 1V into each main rail around MAX77620 with that IC removed. That would tell you which rail was shorting as well as let the component drawing the current to heat up

It's good to try things ...you confirm the issue is with cpu. Keep the good work

A damaged USB connector can put a direct voltage straight into the CPU killing it instantly. I am finding recently that the switch lite models seem to have a broader range of potential faults compared to the standard switch. I have had to do more re-balling of power management ICs and fuel gauge chips as well as failed mosfets, back-light chips etc. Quite a rabbit hole with these. Karl

i have all these same problems on the board im currently trying to fix, literallly didi every step you had done (before watching your video as it was driving me insane and came to youtube to see if i was missing somthing obvious) but more to my point did you ever do a follow up on this or was it just dead cpu and used as a donor board or did you find another issue/correct isssue before i put this away as a donor becuase ive been testing this bi tch board for 4 days now haha

ouch and better luck next time on your next repair

After watching some YT Shorts from TronicsFix i'm starting to think that either these repair shops ain't even trying to repair stuff or they just don't know how to actually do this :P But in the end we still can celebrate Your little success! At least we can assume what is the problem here :D

Haha, this is actually mine. I had a hell of a time with the repair shop and was fobbed off multiple times before I managed to get it back. It was completely disassembled and thrown in a plastic takeaway tub. Way beyond my skill to repair

Are CPU's bound to the board ? It wouldn't work resoldering the cpu from some other board ?

whoever worked on that before you definitely had no idea wtf they were doing. as much of an amateur as i am at repairs, i for one would still make sure i installed all the screws and definitely wouldn't forget the fans and heat shield, the original owner hopefully got their money back fromt he clear scammers who had the device and "repaired" it

how would u know the cpu is dead when u havent soldered it back on, but i guess it would be hard without a stencil

Shame that the CPU is dead. But I'm sure you'll be able to get another quite easily now. I think the next step Joey is getting a stencil and going for the reball! Great video as always! One favour though please make a pinned comment each video as sadly I glanced down at my phone and seen the outcome before I watched the video 😅😅😅

The repair from the shop was pretty bad.. but it was really interesting to see the underneath of the CPU.

Aren’t those so called caps around the max chip actually inductors hence low impedance.

The cpu is married to the motherboard? There is any posibilities to put another cpu from a donor board?

I hope you didn't lose to much money on the switch. Maybe you can send this one to the coder muhaha maybe he knows some crazy repair. Muhaha you talk about him 1 min after I commented. Hé's the wildest repairman. Also the thermal paste man but I feel the coder is the specialist for this kind of stuff.

Wouldn’t surprise me if the shop in question has bad reviews looking at the state of that port

Never remove parts based on a guess. Always inject voltage on the shorted net and feel for heat.

What if you get a re-balled CPU? Can you give it a try? Nice job by the way...

I think it should not call its self a repair shop as from the repair they did looked like a blind cobbler did it lol

The repair shop might have ruined that switch to be honest, a short might have killed the cpu, thats what happens lots of times in switches, if it has a bad charging port or shorted port sometimes high voltage goes to the cpu and kills it, it could have died before going to the repair shop but they could have also broken it in that repair shop

No technician tried to fix that console but a butcher.

That repair shop sitting their ass on the Lite for 4 months, just to do a mediocre job at swapping the charging port and not even put any screws back in is disgraceful. If you cannot fix it, then just admit to that. Not every repair is doable. Just charge a fee for the attempt and return the Switch fully assembled. That's the bare minimum. At least it gave all of us, and you, a good learning experience.
